eBay Beginner Guide 2026 - Returns, Cassini, Pricing & Scams (UK)

A short, practical guide for new UK eBay sellers covering the topics that matter most: returns handling, the Cassini algorithm, scams to avoid, pricing strategy, Seller Hub basics, and how to start selling from £0.

1. Returns handling - keep it simple and fair

Returns are one of the biggest drains on time and profit. Set clear policies early and automate wherever possible.

1. Set a clear policy: For beginners, start with returns accepted within 14 days. Offer free returns only on high-value or fragile items - they improve conversion but cut margin.
2. State it in the listing: Add a short returns line in your description. This reduces disputes before they start.
3. Pack for returns: Keep spare padded bags ready. If a return arrives damaged, photograph everything before accepting the refund.
4. Respond within 24 hours: Quick, polite responses de-escalate most issues. Offer evidence (photos, tracking) and consider a partial refund if it saves time.
5. Track return reasons: Log them in a simple spreadsheet. If you see a pattern, update your listing copy or photos.

2. Cassini algorithm - what to optimise

eBay's Cassini search ranks listings using relevance and seller performance signals. Influence it with these repeatable actions:

1. Titles & keywords: Put the most searchable terms first - brand, model, colour, size. Avoid filler words. Use UK spellings.
2. Item specifics: Complete every relevant field. Cassini indexes these and boosts visibility in filtered searches.
3. Pricing & postage: Cassini rewards listings that convert. Test prices and postage options; faster delivery often improves ranking.
4. Photo quality: High-quality images that match search intent drive clicks and sales - Cassini notices conversion signals.
5. Seller performance: Low cancellation and return rates, fast dispatch, and good communication lift all your listings.

3. Scams to avoid - protect your account

Scams evolve every year. Watch for these in 2026:

1. Phishing emails: Genuine eBay messages come from @ebay.co.uk or @ebay.com and include personalised details. When in doubt, check messages inside your eBay account.
2. Off-platform payments: Never accept payment outside eBay. Use eBay-managed payments to keep seller protections intact.
3. Return fraud: Photograph items and note serial numbers before packing. Require photos for high-value returns.
4. Chargeback scams: Keep all records - tracking, photos, buyer messages - and submit evidence promptly if a chargeback is raised.
5. Overpayment / courier impostor: Ignore messages claiming you need to refund a shipping overcharge or hand cash to a courier. Verify everything through your eBay messages.

4. Pricing strategy - simple rules that work

1. Research completed listings: Use eBay's completed listings filter to see what actually sold, not just current listed prices.
2. Psychological pricing: Use £X.99 where sensible but prioritise margin. Small items often perform better with free postage baked in.
3. Start with an intro price: List slightly lower for fast turnover and relist with minor tweaks if unsold after 7-10 days.
4. Enable Best Offer: Set a floor price and auto-decline low bids to capture buyers unwilling to pay full price, without wasting your time.
5. Factor all fees: Calculate your final margin after eBay fees, payment processing, and postage before pricing.

5. Quick Seller Hub guide

1. Listings tab: Edit titles, quantities and prices in bulk using the bulk editor.
2. Orders tab: Mark dispatched with tracking promptly - this protects you in disputes.
3. Performance: Check metrics weekly: late dispatches, cancellations, return rates. Fix root causes.
4. Promotions: Use percentage-off or multi-buy promotions to clear slow stock - watch the margin impact.

6. Starting from £0 - how to begin

1. Sell unwanted items: Start with books, clothes, small homewares from around the house. No upfront cost - reinvest profits.
2. Free photography: Natural window light and a plain background work well for most items.
3. Buy low, sell higher: Charity shops, car boots, Facebook Marketplace - hunt for underpriced items to flip.

Short, focused actions beat long plans. Pick one improvement today - update item specifics and the title for a single listing. Check performance after 7 days and iterate.
